Guiseppe98 Posted July 4 Report Share Posted July 4 2013 ford edge SEL AWD. never had an issue with power steering prior to work done for a PS Leak. Currently, Low moaning sound while idling & annoying whining when turning the wheel at slow speeds. Noise still persists after the followiny work was performed: - new aftermarket rack/pinion - new aftermarket pump (which failed after the new rack was installed so we had installed another OEM pump. - new high pressure line - return line repair for minor hole. - new belts, belt tensioner - system air bleed by 2 different shops and on my own with jack stands, vacuum pump and turning the wheel 600 times. - figure 8 driving lock to lock There is no active leak. The PS fluid (ATF) has no bubbles in the reservoir. I'm completely baffled and the only thing shops are offering is getting a new rack/pinion and pump because the system is contaminated. https://photos.app.goo.gl/sfibhm6QPMGm9sYb9 Anyone else have this issue? 1 Quote Link to comment Share on other sites More sharing options...

garycrist Posted July 8 Report Share Posted July 8 Look for how to bleed a power steering system. Your problem arises from air in the system. The older systems with hose clamps on the return or low pressure side were notorious in allowing air to get sucked in with no fluid leaks. On occasions a vacuum is used to help draw air out of the system.. GL Quote Link to comment Share on other sites More sharing options...
Guiseppe98 Posted October 2 Author Report Share Posted October 2 SOLUTION We ended up replacing the Rack & pinion, PS Pump with new OEM, the noise continued. Then the mechanic realized that early on he changed the PS high pressure line to an aftermarket. Well, he ordered an OEM High pressure line, installed it, bled the line and boom - the whining was gone. all that time, money and energy was the result of an Aftermarket High pressure line. I truly hope this helps someone else down the road. Joey 1 Quote Link to comment Share on other sites More sharing options...
